Do Exports Raise Productivity? Plant-level Evidence from the Colombian Agri-food Industries AgEcon
Kandilov, Ivan T.; Liu, Xiangping.
Using detailed plant-level manufacturing Census data from the Colombian Agri-food industries, we show that exports raise plant-level productivity by about 15 to 20 percent. However, the estimates reveal that efficiency in plants that become persistent exporters, i.e. plants that service foreign markets at least 30 percent of the time during our sample years 1981-1991, increases about 30 percent upon their entry into foreign markets, while productivity in plants that become only occasional exporters does not change at all. Hence, the positive impact of exports on productivity for is driven by the large positive impact on persistent exporters. To identify the effect of exports on plant-level productivity we employ the Levinsohn-Petrin (2003) measure of...

The Impact of Broadband on U.S. Agriculture: An Evaluation of the USDA Broadband Loan Program AgEcon
Kandilov, Amy M.G.; Kandilov, Ivan T.; Liu, Xiangping; Renkow, Mitch.
We evaluate the impact of USDA’s low-cost broadband loan programs on the U.S. agricultural sector. The broadband loan programs increase access to high-speed internet in recipient communities, which can raise farm sales by increasing both farm output and prices received by producers. Further, high-speed internet may drive down costs by providing information on cheaper inputs and better management practices, leading to an overall improvement in farm profits. Using data from the 1997, 2002, and 2007 U.S. Census of Agriculture, we employ a panel difference-in-differences estimator, as well as a difference-in-differences propensity score matching estimator, to show that the two USDA broadband loan programs have positive impacts on farm sales, expenditure,...

Do Agricultural Preservation Programs Affect Farmland Conversion? Evidence from a Propensity Score Matching Estimator AgEcon
Liu, Xiangping; Lynch, Lori.
More than 124 governmental entities concerned about suburban sprawl and farmland loss have implemented farmland preservation programs preserving 1.67 million acres at a cost of $3.723 billion. Yet little analysis on these programs' effectiveness in slowing farmland loss has been conducted. Using a unique 50-year 269 county panel data set on preservation programs and farmland loss for six Mid-Atlantic States, we employ the propensity score matching method to find strong empirical evidence that these programs have had a statistically significant effect on the rate of farmland loss. Preservation programs on average decrease the rate of farmland loss by 3 percentage points; a 43% decrease from the average rate of 7.31%.

Do Agricultural Preservation Programs Affect Farmland Conversion? AgEcon
Liu, Xiangping; Lynch, Lori.
More than 124 governmental entities concerned about suburban sprawl and farmland loss have implemented farmland preservation programs preserving 1.67 million acres at a cost of $3.723 billion. We ask how effective are these programs in slowing the rate of farmland loss. Using a unique 50-year 269 county panel data set on preservation programs and farmland loss for six Mid-Atlantic States, we employ the propensity score matching method to find strong empirical evidence that these programs have had a statistically significant effect on the rate of farmland loss. Preservation programs on average decrease the rate of farmland loss by 2.4 percentage points; a 33% decrease from the average 5-year rate of 7.31%.

Does Targeting a Designated Area Crowd out the other Preservation Programs’ Efforts? AgEcon
Liu, Xiangping; Lynch, Lori.
Maryland has introduced a number of land preservation programs over the past 40 years to permanently preserve resource lands. Although new programs can increase the number of acres being preserved, they might have unintended impact on land preservation due to interaction with existing land preservation programs. The Maryland Rural Legacy program began in 1997 by designating large contiguous blocks of land and focusing its preservation efforts only in those areas. The program’s could attract existing programs to shift their preservation effort into this designated rural legacy areas if there exist economy of scale or they subsidized existing programs’ effort through matching funds. Alternatively, it could crowd out the others’ preservation efforts in these...
